体内研究:
Tylvalosin tartrate (160 mg/kg; po; 7 d) 可以减轻 PRRSV 灭活疫苗免疫过程中猪的应激状态并改善猪的健康情况。Animal Model:PRRSV-free commercial breed piglets
Dosage:800 mg/kg Aivlosin (20% Tylvalosin Tartrate Premix)
Administration: po; 7-14 days
Result:Attenuated the increase in total white blood cells induced by immunization at day one post-immunization (DPI) and induced an increase in monocyte counts after seven DPI.Attenuate the reduction in the percentage of CD8+ T cells induced by PRRSV-inactivated vaccine immunization at seven DPI.

体外研究:
Tylvalosin tartrate (10 μg/mL; 0.5, 1 h) 增加猪中性粒细胞中的 Caspase-3 裂解,导致细胞凋亡期间 DNA 断裂。Tylvalosin tartrate (0.1-10 μg/mL; 0.5 h) 促进巨噬细胞对猪中性粒细胞的胞吞作用,而不改变吞噬作用。
